Sony PlayStation 3 Slim warranty void stickers set, full set 2 pieces.

These are primarily meant for repair stores which offer 12-24 month warranties from a repair service they carry out to ensure if the customer ever returns they can check if the damage or fault was caused by the customer opening up the console, the other main use is people use them to make the console eligible for trade in for cash or store credit in places like CEX, GAME, and Cash-converters as one of the first things they check for is system tampering ie the removal of warranty stickers or missing parts.
